| 摘 要： | 以辐射度量为标准,从目标信号、背景信号差值与探测器噪声比值的角度出发,变换凝视型红外搜索跟踪系统的作用距离模型,建立了CCD搜索跟踪系统点目标的作用距离方程。解决了目标为发光体、反射体,以及CCD为不同灵敏度表述方式的跟踪系统的作用距离计算,实例验证计算值与实测值相吻合,为CCD跟踪系统的设计和性能评估提供了理论依据。

| Abstract: | With radiometry as a standard and embarking from target signal, background signal difference and noise ratio of detector, the operating distance equation of a CCD searching and tracking system for point targets is established by transforming the operating distance model of a staring IR searching and tracking system. This solves the calculation for operating distance of a CCD tracking system when targets are luminophor, or reflectors as well as CCD with different sensitivities. The practical examples demonstrate that the calculation values are consistent with the practically measured values. This provides a reference basis for the design and performance evaluation of a CCD tracking system. |
